 Thermal cut-out
The SB-5000 features a function that offers protection against damage 
to the flash panel and body from overheating. This function does not 
stop the flash head temperature rising. Be careful not to let the SB-5000 
overheat during continuous flash use.
•  The thermal cut-out indicator appears when the temperature of the 
flash head rises as a result of the flash being fired numerous times in 
quick succession. All operations except power ON/OFF and menu 
settings are suspended to prevent heat damage to the flash panel and 
body.

•  Wait until the SB-5000 cools down.
•  Operation can be resumed once the warning is no longer displayed.
•  On rare occasions, the thermal cut-out indicator might appear or 
disappear without the temperature changing depending on the zoom 
head position. This is not a malfunction.
